boeing gets faa approval for battery fix on 787 dreamliner - lithium ion rechargeable battery

After a three-
Boeing Dreamliner suspended in the United States for a month. S.
The Federal Aviation Administration gave the company the green light to solve the lithium-ion battery problem.
For Boeing, this is a key step in gaining national status. of-the-
On January, 50 Boeing 787 aircraft were grounded after two accidents, including a battery fire.
"The FAA will require the operation of 787 of airlines to install sealing and ventilation systems for primary and auxiliary system batteries and replace the batteries and their chargers with improved components, federal agencies said at a press conference on Friday.
Ray Lahoud, transport minister, said: "Our top priority is to protect the safety of the tourism public.
These changes to the 787 battery will ensure the safety of the aircraft and its passengers.
Boeing shares soared in the news, rising more than 2 percentage points to close at $87. 96 (U. S. )
In New York, although investigators have not yet identified the cause of the overheating of the battery.
Michael Huerta, FAA administrator, said certified experts observed rigorous testing and spent weeks reviewing detailed analysis of design changes to make this decision.
The FAA will closely monitor the revision work in the United States and will send a team of inspectors to other locations where the revision work will take place.
"Any recovery service for the revised 787 will be carried out after the FAA accepts the work," the press release added . ".
The FAA's rare ban on flying Dreamliners has cost Boeing millions of dollars, some estimated at $0. 6 billion.
Engineers are scrambling to find a solution for Boeing's insistence on changing aircraft for air travel.
Boeing said its team of experts spent more than 100,000 hours working out a test plan, building a test platform, testing and analyzing the results to ensure that the proposed solution meets all requirements. The fuel-

There are fewer passengers in the case of distance routes.

Popular routes that may not attract so many passengers.
Aircraft rely more on electronic systems than any other aircraft, rather than hydraulic or mechanical systems.
This is also the first passenger plane to use lithium-ion batteries widely, and lithium-ion batteries are lighter, faster to charge and more energy than other types of batteries.
Ray Conner, president and CEO of Boeing commercial aircraft, said in a press release that the fix was a "comprehensive and permanent solution with multi-layer protection.
The new housing "will ensure that even if the battery fails, it will not have an impact on the aircraft and will not catch fire," he added . ".
We have the right solution and we are ready.
According to Reuters, Boeing has formed a team and battery kit to transform the existing aircraft. engineers need about four to five days to install each new battery, starting from Japan, japan Airlines and ANA have half the fleet and allow for a gradual restoration of services.
Other global regulators will also have to approve Boeing's new design, but action is expected to be taken quickly once approved by the FAA.
Eight airlines, including United Airlines, Polish Airlines, Ethiopia Airlines and Qatar Airlines, flew to 787.
In Tokyo, Japan's transport minister, Akihiro Ohta, said the 787 review was about to be completed, but he said it was unclear how quickly the aircraft would resume passenger service.
Joseph De Cruz, professor at Rotman School of Management, said the FAA's decision was an important step.
"For Boeing, they will have to bow their heads and move on," Cruz said . ".
"This is a big setback for Boeing, but I also believe Boeing will recover from this setback.
"It's a good product and a good company.
"I think they are unlucky with the battery," he added . ".
The advantage of Boeing is that airlines are eager to get Dreamliner.
"The plane has a very significant advantage over airlines on both fronts," Cruz said . ".
He said: "Fuel consumption is very important today. it is a very friendly plane for passengers . " He cited better cabin pressure and increased humidity.
"Once people fly on this plane, they will absolutely love it.
This gives the airline a competitive advantage.
"But the grounding has seriously hurt Boeing, which plans to deliver-
Quarterly earnings next Wednesday.
Production for a long time
The long-range jet continues to fly at a rate of 5 per month, but delivery has stopped.
Boeing has a backlog of about 800 aircraft, including 37 ordered by Air Canada, which will deliver seven in 2014.
The National Transportation Safety Commission has arranged twice.
Battery failure investigation hearing in Washington next week.
Among those who are expected to testify are FAA officials and Boeing 787 chief project engineer Mike Sinatra.
The topics covered include the reasons for choosing a lithium-ion battery system and the design and development plan.
Boeing also announced this week that it will send a notice of layoffs to 700 engineers.
The company said the layoffs were the result of the end of development work in 747. 8 and 787-9 jets.
Boeing also announced a 747 slowdown on Friday-
8 procedures, production 1.
75 aircraft per month, lower than the previous two per month, due to the decline in demand.
